I got my period June 23rd it lasted 5 days (normal). After 4 days I was spotting (light pink watery) also with mild cramps in the lower absomen area. Today will be day number 2 of spotting and its not so much. What could it be?

Hormonal imbalance. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.
